_ 3.0 DESIGN FEATURES AND OPERATING PRACTICES Objective This section contains a description of design features and operating practices which, if changed, might have a significant environmental impact. Specification If operating practices or design features are planned which deviate from those described in the bases below, an analysis of their potential environmental impact will be made and a course of action taken to alleviate potentiel adverse impacts. In addition, if the ecology of the river significantly changes at a future date as, for example, by major changes in water chemistry or reintroduction of shad, an analysis of expected impacts and a course of ' action to minimize the impacts will be provided. Bases 3.1 Operation of Mechanical Draft Cooling Tower Natural draf t cooling towers are utilized to cool the large heat load of the condenser. The mechanical draft cooling tower cools a mixture of service cooling water and a small amount of natural draft cooling tower blowdown, which represents a much reduced heat load. The effluent from the mechanical draft cooling tower discharges to the river. For normal operation, one pump will be operated with up to three fans to affect maximum cooling without intentionally discharging below river ambient. The tower will be operated manually by the operator f rom the control room to affect maximum cooling without intentionally discharging below river ambient. As an operator aid, the MDCI can be operated in the automatic mode which shif ts fans to half speed, reduces the number of fans operating and shifts fans operation from cell to cell. The automatic mode is used to help prevent icing of the MDCT while maintaining discharge temperature as close as possible to river water inlet temperature. The automatic control system, however, does not assure compliance with environmental Technical Specifications. The operator will take manual control when necessary to prevent icing or to improve cooling tower operation with regard to discharge temperature. During sustained cold periods, the discharge will average 3 F above river ambient. However, since the tower performance is a function of air wet bulb temperature which can increase much more rapidly than the river temperature, the tower's per-formance can become ineffective. An example would be a sudden warm day while the river is still frozen. At such time the tower is shut down since its operation would result in increasing the discharge temperature. During such periods, the discharge temperature is approximately 10 F above river ambient. For cooldown operation two pumps are operated to pu=p over the mechanical draft cooling tower fill. If the tower is in the automatic mode of operation, it is shifted to manual operation to achieve maximum 1585 220 Amendment Ne. la

cooling at the beginning of cooldown. With average winter weather conditions, the tower discharge is apprcximately 12 F above river ambient at the beginning of cooldown and reduces to approximately 3 F some 12 hours later. Near the end of cooldown the tower may be shifted back to automatic control to preclude freeze-up. 3.2 Chemical Usage This s etion describes the chemicals used in the plant which are discharged to the environment. The equipment in which the chemicals are used along the quantities per batch or rate of continuous discharge and expected discharge frequency are included. 3.2.1 Wa_ter Treatment The clarifier continually receives approximately 0.05 lb. of cationic polyelectrolyte and 0.6 lb. of anionic clay per 1000 gallons of water treated to remove suspended solids f rom the river water. Assuming an average flow of 100 gpm. through the clarifier, sludge containing approximately 60 lb. of clay and 5 lb. of polyelectrolyte plus a highly variable amount of suspended solids removed f rom the river water is blown down from the clarifier each day. The sludge is processed in diatomaceous earth pressure filters and the filtrate is released to the plant river water discharge. The solids component is pressed into dewatered blocks. Their disposal is described under solid waters. A cation - anion string in the cycle makeup demineralizer system uses 2260 lb. of sulfuric acid and 1340 lb. of sodium hydrode for each regeneration. An additional 2350 lb. of sodium hydroxide is required to neutralize the spent regenerants prior to discharge, resulting in 3270 lb. of neutralized sodium sulfate contained in approximately 70,000 gallons of water. Based upon a demineralized water use of 40,000 gallons per day and a production of 300,000 gallons between regenerations, this quantity would be released each 7.5 days. Release rates are based upon flow through the mechanical draft cooling tower. Amendment No. 18 1585 221

Bases The postoperational aquatic biological surveillance program of the Susquehanna River in the vicinity of the Three Mile Island ;;uelear Station will begin upon the issuance of an operating license. The impingement study will determine a baseline number for or;anisns lost at the Three Mile Island Nuclear Station so that the significancs of such loss with regard to the resource can be assessed. The entrain-ment study will determine the types and quantities of plankton, fish eggs and fish larvae entrained in the cooling water systens so that the ef fects of entrain =ent can be predicted. The fish study.till provide the qualitative and quantitative observaticas necessary to describe the present fish population in the vicinity of Three Mile Island, to detect any changes which occur after plant startup, and to determine whether changes, if they occur, were caused by operation of the station. The macro-invertebrate study will serve the sa=e pur-pose as that of the fish study. 4.1.2 Terrestrial 4.1.2.1 Bird I=oaction on Cooline Towers Obj ective The purpose of the bird impaction study is to provide information on mortality and injury to avif auna, if any, resulting fro: imp ac-tien on natural draft cooling towers. Soecification Monitoring of the bases of the cooling towers will be conducted during periods of peak migration under conditions of li=ited visibility. The base of each cooling tower will be searched on mornings following days and/or nights of li=ited visibility, during March to June and September to Nove=ber inclusive. The areas to be searched will include the top of the fill, all ca*. walks,

' ~' sa and the ground around the base of each tower out to a distance of 100 feet from the base. Any d?ad or injured birds found win be collected, identified, and the nenbers and locations will be recorded. On days in which incidents of cortality or injury occur, description of meteorological conditions of the previous day and/or night win be included in the daily log. This program vill be con-tinued for one year. Bases Since some potential exists for bird injury and corta11ty due to impaction on the natural draf t cooling towers, and since the pos-sible levels of this 1:npaction are not known, specific report levels, protection limits or the need for such caeasures cannot be established at this time. The study described herein vill provide infor=ation needed to establish a protection limit or report level or to establish that the measurement of bird i=paction is not necessary due to an insignificant ic: pact. The documentation of bird cortality and injury due to impaccion vill anow an estimate to be made of the effect of the cooling towers on migrating birds. 4.1.2.2 Effects of Cooling Tower Salt Drift on Croos and Natural Vegetation Objective The purpose of the cooling tower salt drift study is to determine r if damage to natural vegetation and crops is occurring from salt drifc. Specification The study areas, at locations indicated on Figure 2, which were used in a vegetational-type napping analysis during preoperatien will be checked I ennually to determine if measurable changes are occurring,in species compositicn, relative abundance and relative dominance of naturally occurring vegetation due to salt drif t. Sa=pling will be done near the station in the predicted area of drif t influence and also in control areas removed from the station.

The study described herein vill provide infor=ation needed to establish a protection li=it or report level or to establish that the =easurement of the drift effect is unnecessary due to insignificant impact. Measure =ent of species cc=pesition,' relative abundance, and relative dc=inance vill deter =ine changes in the natural vegetative cc== unity that may be due to plant cperation. Increases er decreases in cer-tain species should becc=e evident if they do in fact cecur.

h7 - Eases The postoperational aquatic che=ical surveillance progra= of the Susquenanna River in the vicinity of the Three Mile Island Nuclear Statica vill begin upon the issuance of an. operating license. This program is designed to provide quantitative infer ation en chemical discharges frc= the plant. Chlorine discharge concentrations are =enitored centinually by installed plant instru=entatien. It is expected that there vill be no significant difference in the concentration of heavy metals between the plant river water intake and discharge. Potential changes in ecceentraticas of heavy =etals due to passage of water through the plant could result frc= discharge of neutralised regenerant vastes, corresien of river water piping er leakage of corrosion inhibitors. The =etals selected for monitoring were selected based on metals kncvn to be in the river. =aterials used in the ecnstruction of river water syste=s and the ce= position of the cerrosion inhibitor used in the closed eccling syste=s. Since no significant increase in concentrations of heavy =etals is expected, the measure =ent downstrea= is unlikely to be of value in defining the chemical plu=e. The only significant addition of dissolved solids to plant effluent is the discharge of neutralized regenerant vastes frc= the cycle

akeup de=ineralizers. In addition, dissolved solids are concentrated in cooling tower blevdevn due to evaporaticn loss in the ecoling towers. Since limits are placed on discharge of dissolved solids by Specification 2.3 2 and concentratices are =cnitored en a =ini=u

There is expected to be no significant addition of suspended solids to the plant discharge. A period of 1 - 3 years inclusion of this parameter within the postoperaticnal surveillance progra= is cen-sidered sufficient to justify efficiency and reliability of plant 1585 23i A=end=ent No. 18

. filtration equipment, especially since Specification 2.3.2 li=its suspended solids concentrations in the river water discharge and suspended solids concentrations are measured on a minimum weekly frequency during plant operation. 4.2.2 Ambient Water Ouality The water sampling program will be undertaken to monitor the ambient water quality of the Susquehanna River. The program will provide baseline data for the biological program. The samples will be collected on a semi-monthly basis in conjunction with the biological surveillance program (Section 4.1.lE). The following ite=s will be included in the water quality analyses: pH Sog Cl 01: solved 02 Susp. Solids Alkalinity Ca 'Mg Nitrate Nitrogen Na Ortho-phosphate (Sol.) K Phosphate (Total) Fe (Total) Nitrite Nitrogen A==onia Nitrogen Bacterial Analysis - Fecal Coliform Phenol Heavy Metals (listed on page 46) 4.3 Physical 4.3.1 Thermal Pl'u=e Mapoing Objective To provide temperature data for defining the discharge plume and to check the accuracy of the analytical plume =odel. Specification Sampling studies shall be =ade during the first year of operation to identify and characterize the discharge plu=e with respect to tempera-ture. The data shall be collected from a sufficient number of sampling points located to provide a patterned coverage of the pluce. The staff will review the results at the completion of the one year studies to deter =ine if sufficient review and operating condition combinations have been examined and will determine if the studies need to be extended. 1585 232

_. _. _ _ _. _ The studies shall be conducted during conditions of normal and low flows and extreme te=perature conditions to provide the necessary data to validate the analytical plume =odel. k'ind speed and directier measured at the north weather station (I-A-I on Figure 3), air and water temperature and current velocity should be taken concurrently with plume measurements. During the first planned winter coolduwn*" in which an effluent AT > 10*F is expected, and when weather and icing conditions permit monitoring to take place (a " qualifying" cooldown), the 5* AT isotherm shall be located at its widest point to determine size of the zone of passage. If the effluent AT fails to reach 10*F during that cooldewn, the 5*F aT isotherm shall be located again during succeeding" qualifying" cooldowns until the iostherm has been located five times or is measured during a period in which the effluent AT > 10*F. Bases The plu=a mapping will define the temperature gradients in the plume. Special attention will be given to the region near the discharge structure where =omentum and mixing are the prevalent processes influencing the plu=e's horizontal and vertical di=ensions. 4.4 Environmental Radiological Monitoring Obiective An environmental radiological monitoring program shall be conducted to verify that radicaqtive releases are within allowable limits and that plant operations have no detri= ental effects on the environ =ent. Specific'ation a. Environmental samples shall be collected and analyzed according to Table 3 at the locations presented in Figures 3, 4, 5, 6 and 7. b. Reports shall be suba'*ted in accordance with the requirements of Section 5.6 (Plant haorting Require =ents). During the ceasons that animals producing milk for hu=an c. consumption are on pasture, samples of fresh milk will be obtained monthly from these anissis at locations presented in Table 3 and analyzed for their radioiadine content, calculated cs iodine-131. Analysis will be carried out within eight days (one I-131 nalf-lif e) of sa=pling. Suitable analytical procedures will be used to determine the radiciodine concentration to a sensitivity of 0.5 picoeurie per liter of milk at the time of sa=pling. For activity levels at or above 0.5 picoeurie per liter, the overall error (one sig=a ' con #4 dance level) of the analysis will be within i 25%. Results i585 233

Special attention will be paid to those locations where milk is produced for direct consumption by humans - e.g., the family farm. d. A census will be conducted during the =idpoint of the gracing season to deter *e the location of ecvs in potentially affected areas within a five-mile radius of the plant. If it is learned via the census that there are a considerable number of additional locations where milk is produced in the vicinity of the plant, the location (s) may be chosen which serves as a valid indicator of other locations in that meteorological sector, rather than sampling every location. Bases The number and distribution of sampling locations and the various types of measurements described in Table 3, together with the pre-operational bIckground data, will provide verification of the effectiveness of plant effluent control and indication of measurable changes in the activity of the environment. Weekly sa=ples may be missed in the event of adverse conditions such as weather, equipment failure, etc. It is not intended that these missed samples be resampled prior to the next scheduled sample date. Monthly and longer period samples, if missed due to these conditions, will be taken within a reasonable time after the adverse condition no longer exists.
